Error: config flow cant be loaded: undefined

[mitchoklemen]

Hi, I have problem setup smartthings custom. I do install it in HACS, restart HA, but when try to add integration I cant set it up. I get:
Error: config flow cant be loaded: undefined

I did try to uninstall it in HACS, restart and setup the original smartthings but I get same error

Where to start solving?

Thank you, Mitcho
